We'll solve the system using the elimination
method.
We'll note the equations of the system
as:
-2x+3y = 8 (1)
3x-y = -5
(2)
We'll multiply (2) by
3:
3*(3x-y) = -5*3
9x - 3y =
-15 (3)
We'll add (3) to
(1):
9x - 3y - 2x + 3y=
-15+8
We'll eliminate like
terms:
7x = -7
We'll divide by
-7:
x = -1
We'll substitute
the value of x into (2):
3x-y =
-5
-3- y = -5
We'll add 3 both
sides:
-y = -5+3
-y =
-2
y = 2
The
solution of the system is: {(-1 , 2)}.
